Hint: Connection to Docker failed. Is docker or Docker Desktop running?
Thanks in advance. I built the image in docker with the following Dockerfile:
FROM python:3.10
# Set the working directory in the container
WORKDIR /app
# Copy the requirements.txt file and install dependencies
COPY requirements.txt .
RUN pip install -r requirements.txt
# Copy the rest of the application files into the container
COPY . .
# Define environment variable for OpenAI API Key
ENV OPENAI_API_KEY YourOpenAIKeyHere
# Expose port 7860 for Gradio or similar services
EXPOSE 7860
# Start the application
CMD ["python"]
I get the following error on Widows 11 PC, but not Widows 10 PC:

I've been using Google and ChatGPT to try and solve, but the suggestions have not worked.
Any ideas? Thanks!
I get this error on win11 when I run it in git bash instead of wsl. I have dockerd running in wsl only. It can't see dockerd from git bash. The agent needs a docker container as a playground. The controller needs the docker daemon to start containers for agents. If you want to run the python controller itself in a docker container, the container needs access to dockerd.
User can i access dockerd from python inside docker container?
ChatGPT Yes, you can access dockerd (the Docker daemon) from Python inside a Docker container. This is often referred to as "Docker in Docker" (DinD). However, there are different ways to set it up, and there are caveats to consider.
Approaches to Running Docker in Docker Docker Socket Binding (Most Common Approach):
You mount the Docker socket from the host into the container. This allows the container to use the Docker daemon on the host machine. This is done by adding -v /var/run/docker.sock:/var/run/docker.sock to the docker run command when starting the container. Inside the container, you can use Docker CLI commands or a Docker SDK for Python (like docker-py) to communicate with the Docker daemon. Example of mounting the socket:
bash Copy code docker run -v /var/run/docker.sock:/var/run/docker.sock -it your-container Python Example:
python Copy code import docker
client = docker.from_env() containers = client.containers.list() print(containers) DinD (Docker Inside Docker Daemon):
This is a more complex approach where a Docker daemon (dockerd) is run inside the container itself. The Docker team provides a special Docker image called docker:dinD designed for this use case. It works well for CI/CD scenarios or isolated environments where you want a fresh Docker daemon inside the container. Example of running DinD:
bash Copy code docker run --privileged -d docker:dind The --privileged flag gives the container elevated privileges required to run the Docker daemon.
Caveats Security Concerns: Mounting the Docker socket from the host gives the container control over the host's Docker daemon, which is a security risk. The container can start/stop/remove any container on the host and potentially access host resources.
DinD Performance: Running a Docker daemon inside a container can be resource-intensive and may introduce complexity, especially when dealing with networking and storage layers.
Use Cases: Socket binding is more common for development purposes, while DinD is used for building Docker images or running isolated Docker environments inside CI pipelines.
Conclusion Docker in Docker works both with socket binding (simpler and more common) and DinD (more isolated but complex). The best approach depends on your use case.
Thank you for the quick reply, I'll work through your advice and post a follow-up. As far as I can tell I am using WSL, but I also remember seeing a setting on Docker for Bash during install, if I remember correctly.
I'm also getting this error on Mac and apple silicon. Docker info works. Docker run hello-works. But getting:
Error: Traceback (most recent call last): File "/Users/xxxxxx/miniconda3/envs/a0/lib/python3.12/site-packages/docker/api/client.py", line 207, in init self._version = self._retrieve_server_version() ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/Users/xxxxxxx/miniconda3/envs/a0/lib/python3.12/site-packages/docker/api/client.py", line 230, in _retrieve_server_version raise DockerException( docker.errors.DockerException: Error while fetching server API version: ('Connection aborted.', FileNotFoundError(2, 'No such file or directory'))
me too, using Macbook M1 with Sonoma 14.5. Docker is running, but the agent zero fails with the same line error.
Traceback (most recent call last): File "/opt/miniconda3/envs/a0/lib/python3.12/site-packages/docker/api/client.py", line 207, in __init__ self._version = self._retrieve_server_version() ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/opt/miniconda3/envs/a0/lib/python3.12/site-packages/docker/api/client.py", line 230, in _retrieve_server_version raise DockerException( docker.errors.DockerException: Error while fetching server API version: ('Connection aborted.', FileNotFoundError(2, 'No such file or directory'))
any solution?
